The Ford MPFI Coil On Plug Main Harness from HOLLEY is a vital electrical component specifically designed for modern Ford engines that utilize multi-point fuel injection and coil-on-plug ignition systems. This harness is essential for routing high-voltage signals from the powertrain control module (PCM) to the individual coils mounted directly on each spark plug, ensuring reliable spark delivery and engine efficiency.
Engineered with precision-molded connectors and OEM-grade wiring, this harness minimizes electrical resistance and prevents signal degradation under load. The coil-on-plug configuration eliminates the need for traditional distributor caps and long plug wires, which can reduce electromagnetic interference and improve ignition timing accuracy. Its robust construction is designed to withstand the thermal and vibration stresses of modern engine compartments.
This harness is ideal for engine builders, performance tuners, and enthusiasts looking to install modern ignition systems on Ford MPFI platforms or convert older ignition architectures to coil-on-plug technology. Its reliable performance makes it a critical component for anyone upgrading or building a performance engine.
